Installing the Module
Remove system power before removing or installing any module in an I/O
chassis. Failure to observe this warning may result in damage to the mod-
ule's circuitry and/or undesired operation with possible injury to personnel.
Keying Bands
Plastic keying bands can be inserted into the top backplane connector to prevent the insertion
of other modules.

Table 2.2 Transducer Specifications
Transducer Mounting
All AMCI resolver based transducers are designed to operate in the industrial environment
and therefore require little attention. However, there are some general guidelines that should be
observed to ensure long life.
hýLimit transducer shaft loading to the following maximums:
Radial Load Axial Load
All 0.625" Shafts
100 lbs. (445 N) 50 lbs. (222.4 N)
All other Shafts
30 lbs. (133 N) 15 lbs. (66.7 N)
Table 2.3 Transducer Bearing Loads
hýMinimize shaft misalignment when direct coupling shafts. Even small misalignments
produce large loading effects on front bearings. It is recommended that you use a
flexible coupler whenever possible.
